Triac returns to action

After my Triac has been laid up for about 2 years due to doing up a house, building a garage & many other projects.
I finally got round to using it again this week, so thought I would post up a couple of pix of what I've been making.
These are overhead rockers for a 1930's fully radial 250cc Rudge motorcycle.
From the date on my drawing, you will see that I had intended to do these 4 years ago! Such is life!

Nice one Roy, How many Rudge 250s are there out there? What is the material specification?

There probably about 300 + 250cc Rudges still about.
Material is EN36B (3 1/4% Nickel chrome, 65 ton) These will now be hardened .040" deep to 65 HRC, then the side bearing faces surface ground & the bores honed.
Cheers, Roy

300 + Rudge 250's, wow. Its good to see that your are supporting these motor cycles with spare parts, and keeping our heritage up and running, good job.

Very nice work.
Would be interesting to see how you set this cut up, special fixtures i guess but this is an issue that I always find intriguing and the "old guys at the work shop" never stop to amaze me in their smart ways to make their cut. Perhaps you did take a photo during machining?
How long did each part take and what feed rate did you use?
Sorry for all the questions..
